FOOTBALL.

Application filed. December 30, 19241v Serial No. 758,918.

T0 at whom it may concern:

Be it known that I, MAX KASI SER, a German citizen, and residing at Wald, near Solingen, Germany, have invented certain new and useful Improvements in a Football (for which I have made application for patent in Germany on 18th January, 1924, No. K. 881 15 IX/77 of which the following is a specification.

This invention relates to an improvement in footballs of the kind in which the opening of the outer leather case for the inflation nipple of the inner rubber bladder is automatically closed during the inflation of the bladder by means of circumferential leather or the like strips at the inner walls of the leather case. The novelty consists in that said leather strips are kept in parallel position to each other by means of transverse spacing members and are thereby placed at such a distance from each other that in the middle between them sufficient space is left for an unobstructed passage of said inflation nipple through said opening during the inflation and for a storage of said nipple within said case after completed inflation. Besides, the inner wall of the outer leather case is diametrically opposite said opening fitted with a transverse guide piece for said leather strips so as to keep the latter always in their proper position.

The accompanying drawing represents the improvement: Fig. 1 is a perspective view of a. foot-ball fitted with the same, while Fig. 2 is a similar view of the detached means for closing the opening in the football.

The circumferential leather or the like strips 2, 3, 4, 5 at the inner walls of the I outer leather case 1 of the foot-ball are with their ends firmly attached to the boundary leather pieces ('3, 7 enclosing the opening 11 for the inflation nipple 10 of the inner rubber bladder of the foot-ball. Said attachment is effected in such a way that during the inflation of the rubber bladder and consequent stretching of the leather strips 2, 3, 4, 5 in the direction of arrows indicated in Fig. 2, the opening is automatically closed. Said leather strips are kept in parallel position to each other by means of transverse spacing members 8 and thereby placed at such a distance from each other that in the middle between them sufficient space is left for an unobstructed passage of said inflation nipple 10 through said opening 11 during the inflation and for a storage of said nipple within said case after completed inflation. Besides, the inner wall of the outer leather case 1 is diametrically opposite said opening 11 fitted with a guidepiece 9 for said leather strips so as to keep the same always in their proper position.

To prevent a clamping of the inflation nipple 10 during the inflation by the gradually closing edges of the opening 11, a protective insertion of any suitable nature is placed around said nipple and again removed after completed inflation and storage of the nipple within the case 1, whereupon the opening is completely closed by the vigorous stretching action of the leather strips.

What I claim, is:

1. In a football comprising an outer leather case having a closable opening therein and an inner rubber bladder having an inflation nipple thereon: the combination with circumferential leather strips at the inner walls of said case having their ends attached to the edges of said opening so as to automatically close the latter during the inflation of said rubber bladder, of transverse spacing members located to keep said leather, strips in parallel position to and at such a distance from each other that in the middle between them sufficient space is left for an unobstructed passage of said inflation nipple through said opening during the inflation of said rubber bladder and for a storage of said nipple within said case after completed inflation.

2. In a foot-ball as specified in claim 1: a guide-piece for said leather strips fitted on the inner wall of said case diametrically opposite its opening.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

MAX KAYSER.
